An orthopaedic tibial prosthesis includes a tibial baseplate with features designed for use with small-stature knee-replacement patients. The tibial prosthesis may include a shortened tibial keel, tibial keel fins which define a large angle with respect to a longitudinal axis of the keel, and/or tibial keel fins which extend along less than the entire longitudinal extent of the keel.

An osteotomy implant includes a first surface extending generally in a first plane and a second surface extending generally in a second plane, oblique to the first plane. The first surface has a perimeter having a first linear edge, a first curve edge connected to the first linear edge, a second linear edge connected to the first curved edge, and a second curved edge connected to the second liner edge.

Hard-tissue implants are provided that include a bulk implant, a face, pillars, slots, and at least one support member. The pillars are for contacting a hard tissue. The slots are to be occupied by the hard tissue. The at least one support member is for contacting the hard tissue. The hard-tissue implant has a Young's modulus of elasticity of at least 3 GPa, and has a ratio of the sum of (i) the volumes of the slots to (ii) the sum of the volumes of the pillars and the volumes of the slots of 0.40:1 to 0.90:1. Methods of making and using hard-tissue implants are also provided.

An osteotomy implant includes a first surface extending generally in a first plane and a second surface extending generally in a second plane, oblique to the first plane. The first surface has a perimeter having a first linear edge, a first curve edge connected to the first linear edge, a second linear edge connected to the first curved edge, and a second curved edge connected to the second liner edge.

An artificial articulation having stable fixing means for unicompartmental knee arthroplasty is stably attached to the top of a tibia in order to permit a sliding motion of an artificial joint attached to the bottom of a femur. The artificial articulation includes an implant hat part which a curved surface structure that makes surface contact with the artificial joint attached to the bottom of the femur is formed on an upper surface thereof, and protrusions protruding by a predetermined height in a direction of the top of the tibia are formed in large numbers on a lower surface thereof, and a distally extending stem configured to be formed to protrude downward by a predetermined length from the lower surface of the implant hat part, and to be inserted into the tibia by a predetermined depth from the top of the tibia and attached thereto.

An implant for repairing an articular cartilage defect site including an implant fixation portion with an upper segment and at least one bone interfacing segment and a top articulating portion with an articulating surface and an engagement surface. The upper segment includes a supporting plate with a first locking mechanism segment. The engagement surface includes a second locking mechanism segment. The first locking mechanism segment with at least two channels is structured to couple to the second locking mechanism segment with at least two protrusions. The at least one bone interfacing segment structured for insertion into the articular cartilage defect site. An implant including an implant fixation portion, a top articulating portion, and a locking mechanism with a first locking segment coupled to the upper segment and a second locking segment coupled to the at least one engagement surface and structured to couple to the first locking segment.

A bone graft system includes a two-dimensional mesh sheet sized and shaped to, when folded along fold lines, form a three-dimensional graft containment structure configured to be packed with a bone graft material for placement within a target area of a bone, the mesh sheet including a first end flap connected to a remaining portion of the mesh sheet via a first fold line and a second end flap connected to the remaining portion of the mesh sheet via a second fold line, a third fold line extending from the first fold line to the second fold line so that the remaining portion is configured to be wrapped around folded first and second end flaps to form the graft containment structure, the first and second end flaps substantially corresponding to a profile of the target area of the bone.

Various cannulated bone implants and methods of using the cannulated bone implant are disclosed. The cannulated bone implant can include a proximal portion, a proximal end, a distal portion, a distal end, a transition portion, a threaded portion, a finned portion and a central passage. The transition portion can comprise a bend positioned between the proximal portion and the distal portion. The threaded portion can be positioned along the proximal portion between the proximal end and the transition portion. The threaded portion can be configured to secure the implant into a bone of a patient. The finned portion can be positioned along the distal portion between the transition portion and the distal end. The finned portion can be configured to prevent migration and/or rotation of the implant in use. The central passage can extend linearly from the proximal end of the implant to the distal end of the implant.

A spinal implant for insertion into and positioning in an intervertebral space is provided. The insert comprises a compressible support configured to change the height of the insert, wherein the insert comprises a first portion having a first surface and a compressible support adjacent to the first surface; and a second portion having a second surface and a second compressible support adjacent to the second surface. A method for fusing two adjacent vertebrae utilizing the spinal implant including the bone insert is also provided.

In the present disclosure, an artificial joint stem includes a base and a coating film located on the base. The base includes a first region, a second region, and a third region located in sequence. The coating film contains a calcium phosphate-based material and an antimicrobial material. The coating film is located across the first region and the second region, and the third region is exposed from the coating film. The surface of the coating film located in the first region has a larger surface roughness than the surface of the base in the third region.
